Devil Fish (film)

Monster Shark (Italian: Shark - Rosso nell'oceano) is a 1984 science fiction-horror film directed by Lamberto Bava. The film is set at a tourist location along the Florida coastline.

Military scientists race civilian scientists to prevent the secret of their murderous monster's escape from getting out.
